Abstract

There are no standard management protocols for the treatment of bile leak (BL) after liver transplantation. The objective of this study is to describe treatment options for BL after pediatric LT.

Methods: Retrospective analysis (January 2010-March 2023).

Variables studied: preoperative data, status at diagnosis, and postoperative outcome. Four groups: observation (n = 9), percutaneous transhepatic cholangiography (PTC, n = 38), ERCP (2), and surgery (n = 27).

Results: Nine hundred and thirty-one pediatric liver transplantation (859 LDLT and 72 DDT); 78 (8.3%) patients had BL, all in LDLT. The median (IQR) peritoneal bilirubin (PB) level and fluid-to-serum bilirubin ratio (FSBR) at diagnosis was 14.40 mg/dL (8.5-29), and 10.7 (4.1-23.7). Patients who required surgery for treatment underwent the procedure earlier, at a median of 14 days (IQR: 7-19) versus 22 days for PTC (IQR: 15-27, p = 0.002). PB and FSBR were significantly lower in the observation group. In 11 cases, conservative management had resolution of the BL in an average time of 35 days, and 38 patients underwent PTC in a median time of 22 days (15-27). Twenty-seven (34.6%) patients were reoperated as initial treatment for BL in a median time of 17 days (1-108 days); 25 (33%) patients evolved with biliary stricture, 5 (18.5%) after surgery, and 20 (52.6%) after PTC (p = 0.01).

Conclusion: Patients with BL who were observed presented significantly lower levels of PB and FSBR versus those who underwent PTC or surgery. Patients treated with PTC presented higher rates of biliary stricture during the follow-up.
